Inverse medium problem for a singular contrast [PDF]

open access: yes, 2019
We consider an inverse medium problem in two- and three-dimensional cases. Namely, we investigate the problem of reconstruction of unknown compactly supported refractive index (contrast) from L-2 with a fixed positive wave number.

Inverse problems: Dense nodal subset on an interior subinterval

open access: yesJournal of Differential Equations, 2013
The authors consider the inverse nodal problem for the Sturm-Liouville equations defined on the interval \([0,1]\) with separated boundary conditions. They prove that a twin dense subset of the nodal set in an interior subinterval uniquely determines the potential on the whole interval and the boundary condition parameters.

Uncertainty quantification and weak approximation of an elliptic inverse problem [PDF]

open access: yes, 2011
We consider the inverse problem of determining the permeability from the pressure in a Darcy model of flow in a porous medium. Mathematically the problem is to find the diffusion coefficient for a linear uniformly elliptic partial differential equation ...

On the inverse nodal problems for discontinuous Sturm–Liouville operators

open access: yesJournal of Differential Equations, 2016
Recently, a new class of inverse problem so-called inverse nodal problems has attracted the attention of researchers. Inverse nodal problems, in turn, consist in constructing operators from given zeros of their eigenfunctions. In this paper, the authors consider an inverse nodal problem for Sturm Liouville operator with jump condition at the point \(x ...

Approximation of Bayesian inverse problems for PDEs [PDF]

open access: yes, 2010
Inverse problems are often ill posed, with solutions that depend sensitively on data. In any numerical approach to the solution of such problems, regularization of some form is needed to counteract the resulting instability.

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

open access: yesAdvanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.
